In just a couple of years, virtualisation has become one of the most widely used IT industry buzzwords. Google, for example, found ‘about’ 22.5 million mentions in just 0.06 seconds. It has some significant benefits for users — and cost-conscious ones in particular — but it is also a major enabling technology for the next round of systems and operational developments. The primary one, already receiving its fair share of hype, is ‘The Cloud’; and that is arguably just a precursor of a further big technology development — utility services. Virtualisation is, in its own way, playing a major role in what will become a significant change in the way users plan the provisioning of their IT services and resources.
